Description

슬립 조절되는 유압식 차량 브레이크 시스템{Slip-regulated, hydraulic vehicle brake system}Slip-regulated hydraulic vehicle brake system

본 발명은 청구항 제 1항의 전제부에 따른 슬립 조절되는 유압식 차량 브레이크 시스템에 관한 것이다.The present invention relates to a hydraulically controlled hydraulic vehicle brake system according to the preamble of claim 1.

슬립 조절되는 유압식 차량 브레이크 시스템들은 공지되어 있다. 이들은 근력에 의해 작동 가능한 메인 브레이크 실린더를 포함하고, 상기 메인 브레이크 실린더에는 하나 또는 다수의 브레이크 회로가 접속되며, 브레이크 회로에는 각각 하나 또는 다수의 휠 브레이크가 접속된다. 종종 메인 브레이크 실린더는 브레이크 부스터, 대개 저압 브레이크 부스터를 포함하고, 상기 저압 브레이크 부스터는 종종 진공 브레이크 부스터라고도 한다. 전기 기계식 브레이크 부스터도 공지되어 있다. 휠 브레이크들은 통상 브레이크 압력 상승 밸브 및 브레이크 압력 강하 밸브를 포함하는 브레이크 압력 모듈레이션 밸브 장치를 통해 브레이크 회로에 접속된다. 또한, 각각의 브레이크 회로 내에는 브레이크 압력 상승을 위해 그리고 브레이크액을 휠 브레이크로부터 메인 브레이크 실린더 방향으로 반송하기 위해 유압 펌프가 있으며, 상기 유압 펌프는 종종 반송 펌프라고도 한다. 휠 브레이크 압력 모듈레이션 밸브 장치 및 유압 펌프에 의해, 휠 개별적인 브레이크 압력 조절, 예컨대 안티-록 조절, 안티-스핀 조절 및/또는 드라이빙 다이내믹 조절(약어: ABS, ASR, ESP 및/또는 FDR)이 가능하다. 슬립 조절은 공지되어 있으므로 여기서 상세히 설명되지 않는다.Slip-adjusted hydraulic vehicle brake systems are known. These include a main brake cylinder operable by muscle force, one or more brake circuits are connected to the main brake cylinder, and one or more wheel brakes, respectively, to the brake circuit. Often the main brake cylinder comprises a brake booster, usually a low pressure brake booster, which is often referred to as a vacuum brake booster. Electromechanical brake boosters are also known. The wheel brakes are typically connected to the brake circuit via a brake pressure modulation valve device comprising a brake pressure rise valve and a brake pressure drop valve. Also within each brake circuit is a hydraulic pump for increasing the brake pressure and for conveying the brake fluid from the wheel brake towards the main brake cylinder, which is often referred to as a conveying pump. Wheel brake pressure modulation valve arrangements and hydraulic pumps enable wheel individual brake pressure adjustments such as anti-lock adjustment, anti-spin adjustment and / or driving dynamic adjustment (abbreviations: ABS, ASR, ESP and / or FDR). . Slip adjustment is well known and will not be described here in detail.

공개 공보 DE 10 2004 027 508 A1에는 각각의 브레이크 회로 내에 유압 펌프 대신에 2개의 브레이크 회로에 대한 공통 유압 펌프를 포함하는, 슬립 조절되는 유압식 2 회로 차량 브레이크 시스템이 개시되어 있다. 유압 펌프의 흡입 측은 메인 브레이크 실린더 상에 놓인, 무압력 브레이크액 저장 탱크에 직접 접속되고, 상기 저장 탱크는 (무압력) 유압 축압기로도 이해될 수 있다. 또한, 유압 펌프의 흡입 측은 솔레노이드 밸브를 통해 2개의 브레이크 회로에 접속된다. 유압 펌프의 압력 측에 유압 축압기, 즉 축압기가 접속되며, 상기 축압기에는 축압기 밸브라고 하는 솔레노이드 밸브를 통해 2개의 브레이크 회로들이 접속된다. 유압 펌프는 브레이크액을 축압기 내로 송출함으로써, 압력 하의 브레이크액이 메인 브레이크 실린더의 작동과 관계없이 브레이크 작동을 위해 제공된다. 공지된 차량 브레이크 시스템은 매우 신속한 브레이크 작동을 가능하게 하는데, 그 이유는 브레이크 압력이 미리 상승될 필요가 없고, 유압 축압기 내에 제공되기 때문이다.Published DE 10 2004 027 508 A1 discloses a slip regulated hydraulic two-circuit vehicle brake system comprising a common hydraulic pump for two brake circuits instead of a hydraulic pump in each brake circuit. The suction side of the hydraulic pump is directly connected to the pressureless brake fluid storage tank, which is placed on the main brake cylinder, which can also be understood as a (pressureless) hydraulic accumulator. In addition, the suction side of the hydraulic pump is connected to two brake circuits via a solenoid valve. A hydraulic accumulator, that is, an accumulator, is connected to the pressure side of the hydraulic pump, and two brake circuits are connected to the accumulator through a solenoid valve called an accumulator valve. The hydraulic pump delivers the brake fluid into the accumulator, whereby the brake fluid under pressure is provided for brake operation regardless of the operation of the main brake cylinder. Known vehicle brake systems enable very fast brake actuation because the brake pressure does not have to be raised in advance, but is provided in the hydraulic accumulator.

본 발명의 과제는 매우 신속한 브레이크 압력 상승을 가능하게 하는 것이다.The problem of the present invention is to enable very rapid brake pressure rise.

상기 과제는 청구항 제 1항의 특징들을 포함하는 차량 브레이크 시스템에 의해 해결된다.The problem is solved by a vehicle brake system comprising the features of claim 1.

청구항 제 1항의 특징들을 포함하는, 본 발명에 따른 슬립 조절되는, 유압식 차량 브레이크 시스템은 각각의 브레이크 회로에 존재하는 유압 펌프에 추가해서 추가 펌프를 포함하며, 상기 추가 펌프의 압력 측에는 하나 이상의 휠 브레이크 또는 하나 이상의 브레이크 회로가 접속된다. 추가 펌프는 유압 펌프이며, 기본적으로 브레이크 회로 내의 유압 펌프와 동일한 구성을 가질 수 있지만, 다른 구성을 가질 수도 있다. "추가"라는 표현은 펌프의 명확한 표시 및 브레이크 회로의 유압 펌프들의 구별을 위해 사용되며, 이 펌프가 브레이크 회로 내에 존재하는 유압 펌프에 추가해서 제공된다는 것을 나타내야 한다.The slip-adjusted hydraulic vehicle brake system according to the invention, comprising the features of claim 1, comprises an additional pump in addition to the hydraulic pumps present in each brake circuit, at least one wheel brake on the pressure side of the additional pump. Or one or more brake circuits are connected. The additional pump is a hydraulic pump and can basically have the same configuration as the hydraulic pump in the brake circuit, but may have other configurations. The expression "addition" is used for a clear indication of the pump and for the distinction of hydraulic pumps in the brake circuit, and should indicate that this pump is provided in addition to the hydraulic pump present in the brake circuit.

추가 펌프는 매우 신속한 브레이크 압력 상승을 가능하게 하고, 이는 사고 방지, 사고 결과 감소 및 드라이빙 다이내믹 조절을 위해 필요하거나 또는 어쨋든 바람직하다. 즉, 높은 브레이크력의 신속한 형성이 결정적인 장점인 브레이크 조절에 바람직하다.Additional pumps allow very rapid brake pressure rise, which is necessary or desirable for accident prevention, accident consequence reduction and driving dynamics adjustment. That is, the rapid formation of high brake force is desirable for brake adjustment, which is a decisive advantage.

본 발명의 장점은 기존 차량 브레이크 시스템이 변함없이 유지될 수 있으며, 브레이크 회로들 중 하나의 브레이크 회로만이 추가 펌프의 압력 측에 접속되면 된다는 것이다. 이 때문에, 본 발명은 적은 비용으로 기존 차량 브레이크 시스템에 구현될 수 있다.An advantage of the present invention is that the existing vehicle brake system can remain unchanged, and only one brake circuit of the brake circuits needs to be connected to the pressure side of the additional pump. Because of this, the present invention can be implemented in existing vehicle brake systems at low cost.

본 발명의 다른 장점은 다회로 차량 브레이크 시스템의 브레이크 회로들의 유압식 분리가 저하되지 않거나 오히려 상승된다는 것이다.Another advantage of the present invention is that the hydraulic disconnection of the brake circuits of a multi-circuit vehicle brake system is not degraded or raised.

본 발명의 추가 장점은 슬립 조절되는 유압식 차량 브레이크 시스템에 사용되는 바와 같은 유압 펌프가 추가 펌프로서 사용될 수 있다는 , 즉 기존 부품이 사용될 수 있다는 것이다.A further advantage of the present invention is that hydraulic pumps as used in slip controlled hydraulic vehicle brake systems can be used as additional pumps, ie existing parts can be used.

종속 청구항들은 청구항 제 1항에 제시된 본 발명의 바람직한 실시예 및 개선예를 제시한다.The dependent claims present preferred embodiments and refinements of the invention as set forth in claim 1.

이하, 본 발명이 도면에 도시된 실시예를 참고로 상세히 설명된다.
도 1은 본 발명에 따른 슬립 조절되는 유압식 차량 브레이크 시스템의 유압 회로도.Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

도면에 도시된 슬립 조절되는 유압식 차량 브레이크 시스템(1)은 2개의 브레이크 회로(Ⅰ, Ⅱ)를 포함하고, 상기 브레이크 회로들은 2 회로-메인 브레이크 실린더(2)에 접속된다. 실시예에서, 2개의 휠 브레이크(3)는 각각의 브레이크 회로(Ⅰ, Ⅱ)에 접속되고, 2개의 브레이크 회로(Ⅰ, Ⅱ)의 수, 및 브레이크 회로(Ⅰ, Ⅱ) 마다 2개의 휠 브레이크(3)의 수는 본 발명에서 필수적이다.The slip-adjusted hydraulic vehicle brake system 1 shown in the figure comprises two brake circuits I and II, which brake circuits are connected to a two circuit-main brake cylinder 2. In the embodiment, two wheel brakes 3 are connected to respective brake circuits I and II, the number of two brake circuits I and II, and two wheel brakes per brake circuit I and II. The number of (3) is essential in the present invention.
